SANITARY can.

Application filed February 14, 1924, Serial no, 599,676. Renewed October 3, 1927.

This invention relates broadly to sheet metal cans of the socalled sanitary type, and it has for its primary object to provide a can of the character commonly employed as containers for coffee, lard and other nonliquid products, which has a readily re1novable cap 01' cover and which is provided with a simple and inexpensive guard whereby chance removal or said cap or cover is efiectually prevented.

A further object. is to provide a can oi the character mentioned which, following removal of its original non-liquid contents, may be employed by the housewife in the manner of ordinary forms of sanitary cans for preserving fruits, vegetables and "the like.

In describing the invention in detail, ref erence is herein had to the accompanying drawings, in which- Figure 1 is a vertical section of the head end of a can embodying my invention a Figure 2 is a top plan View of the same; and- Figure 3 is an enlarged detail section of the cover and the retaining means therefor arranged in operative relation.

Referring to said drawings, 1 indicates the body of the can, and 2 designates the can head which is annularly'attached to the end of the can body through the intermediacy of a double seam 3, as ordinarily. Said head has therein a centrally disposed opening or mouth defined by an upright neck 4-. adapted to have closely fitted thereon a cap or cover 5 of an ordinary form, the latter having an annular downwardly extending neck-embracing rim 5 terminated by a slightly flared edge 5.

Said can head 2 has an outer annular wall which seats closely against the internal face of the can, body 1, extending downward a considerable distance below the double seam 3, The body portion of said head 2, which extends inward from the wall 2 and is terminated by the upright neck a, generally considered, is downwardly and inwardly inclined, so that said neck rises from a level somewhat lower than that of said wall. While said body portion of said head might be located in an inclined plane extending from the wall 2 to the neck 4, it is preferred that said portion be shaped to provide an outer horizontal ledge 2 occupya ing a higher level than does the inner, or neck-encircling, part of said head body, which also disposed horizontally, a more or less abrupt bend 2 being formed between said outer and inner horizontal areas.

Mounted within the channel-like space between the wall-2 of the can head 2 and the fully seated cap or cover 5 is a sheet metal sealing ring 6 of shallow trough-like form in cross section, the bottom-like body there of being disposed horizontally and having its outer and inner edge portions 6 and i5 rising vertically from said bottom. The outer portion ofsaid bottomdike body of the sealing ring seats upon the ledge 2 thecan head, while the inner portion thereof overhangs the inner, orineck encircling, part or saidhead, having the inner anglethereof seated with respect to the flared edge 5 ot the cap or cover, as shown, the distance be tween the levels or said ledge and said, neckencircling part being preferably somewhat in excess of the thickness of the metal of said flared edge.

The cap'or cover5 and the sealing ring 6 are seated in their respective places prior to mounting the head 2 on the'can body; Said head is double seamed on said can body in the usual manner, the seaming dies or rollers operating as ordinarily except that the inner roller acts against the inner face of the outerupright edge portion of the ring 6 and that the double-seaming pressure of the outer die or roller acts to force inward the upper portion of the double seam 3 to the extent that the portion of the outer upright wall 2 of the can head 2 slightly overhangs the adjacentedge of said to said neck.

Provided in the body portionof the ring 5 is a recess or aperture, as 7,'adapted for receiving the end of a pointed instrument whereby a prying force may be exerted for effecting removal of said ring. Following removal of the ring, the cap 5 may be de- 5 and the ring 6 shall be applied by the manufacturer and that the bottom of the can (not shown) he applied by the packer in the usual manner of double seaming following filling of the can.

Following removal of the contents of the can, the latter may be re-used by the housewife in the manner of ordinary-forms of cans for preserving fruits, vegetable etc. In such case, the use of the ring is dispensed with and the channel of the can head 2 adjacent to the flange-like edge of the cap is filled, or partially filled, with sealing wax or a suitable sealing cement whereby access, of air beneath the cap to the contents is prevented.

lVhat is claimed is-- y 1. A can of the character described, comprising a can body, a head double seamed upon an end of said body and having an upright annular wall seated interiorly of said body below the scam, said head also having an upright circular neck spaced inwardly from said annular wall and defining a centralmouth, a mouth-closing cap fitted upon said neck with a depending rim embracing the latter, and an endless sheet a metal retaining ring of shallow trough-like form fitted wholly within the channel between and having frictional engagement with said rim and the annular wall of said head, said double seam being inwardly pressed into holding relation to the adjacent edge of said ring.

2. A can of the character described, comprising a can body, a head double seamed upon an end of said body and having an n right annular wall seated interiorly of said body below the seam, said head also having an upright circular neck spaced inwardly from said annular wall and defining a central month, said head also having the porfor the reception of an end of an unseat-v ing tool.

3. A can of the character described, comprising a body, a head seamed to said body and having an a )right annular wall seated interiorly thereot and extending to a level below the seam, said head also havin an upright circular neck spaced inwardly 30m said annular wall and defining a central mouth, a mouth-closing cap having a depending rim fitted in embracing relation to said neck, and an endless sheet metal ring of shallow trough-like form fitted within the channel formed between said rim and the annular wall of the head and secured in place by an overlying portion of said annular wall.

In testimony whereof, I afiix my signature.
